How serious is the terror threat?

When the State Department ordered the closure of U.S. diplomatic posts due to an al-Qaeda threat on Friday, a spokeswoman called the move a "precautionary measure."

"They attacked our consulate, they killed an ambassador…and nobody’s paid a price. After Benghazi, these Al Qaeda types are really on steroids, thinking we’re weaker and they’re stronger," Graham said on CNN's "State of the Union." "This is an effort to terrorize us, to drive us out of the Mid East. And if we take the bait and try to come home and create a fortress America, we'll have another 9/11."
